4.3. Components of AHB-Lite Architecture

Try these first

1. 1.

   What device serves as the Bus Master in AHB-Lite?

   Hint

   Think of the device that initiates transactions.

2. 2.

   What is the role of a Bus Slave?

   Hint

   Consider what happens after the master sends a command.

3. 3.

   What role does the Bus Master play in AHB-Lite?

   • Initiates transactions
   • Responds to commands
   • Decodes addresses

   Hint

   Think about the flow of information.

4. 4.

   True or False: AHB-Lite supports multiple masters simultaneously.

   • True
   • False

   Hint

   Consider the design focus on simplicity.

5. 5.

   Design a 4-component AHB-Lite architecture for a simplified microcontroller system. Provide a brief description of how data would flow in this setup.

   Hint

   Sketch the architecture and label each component. Describe the transaction sequences.

6. 6.

   Discuss the potential drawbacks of using AHB-Lite’s single master approach in a scalable system design. What implications could arise if future expansion involves adding multiple bus masters?

   Hint

   Consider performance issues and transaction handling when multiple initiators exist.
